Advanced Features Yet Easy to Use
TIG and Stick from One Power Source
The user interface makes machine setup easy. Available features,
such as Pulse, which provides a drumbeat-like rhythm for filler metal
deposition, make you become a better TIG welder – faster.
The multi-process machine can TIG weld when precision and bead
appearance are important. Users also have the advantage of stick
welding capability for outdoor work or thicker materials.
A Great TIG Machine for Aluminum
Take it Everywhere, Plug in Anywhere.™
For a wider or tighter welding bead, users can easily adjust AC
Frequency Control. AC Balance can be adjusted to provide more
cleaning action on dirty aluminum or to maximize penetration
on thick materials.
Plug in the Square Wave TIG 200 where you need it – a standard
120V circuit or 230V for maximum output. Portable and convenient
to use, only 46 lb (21 kg).

Setting
Range
AC Frequency
60-150 (Hz)
A lower frequency results in a wider bead
A higher frequency results in a more
focused bead
AC Balance
60-90 (%Electrode Negative)
A lower AC Balance (%EN) results in an arc with
increased cleaning action
A higher AC Balance (%EN) results in an arc with
higher penetration
Pulse
0.1-20 (Pulses per second)
Lower pulse frequency helps moderate
filler metal deposition
A higher pulse frequency helps manage heat input
and minimize material distortion
